Abstract
An industrial roll includes: a substantially cylindrical shell having an outer surface; a polymeric cover circumferentially overlying the shell outer surface; and a sensing system. The sensing system includes: a plurality of sensors embedded in the cover, each sensor configured to sense a data parameter; and a plurality of wireless transceivers, each transceiver connected to a respective sensor and embedded in the cover adjacent thereto. Each wireless transceiver is configured to transmit data signals from the respective sensor. Related methods and systems are also discussed.
